Modular Lawn Leveller for Lawn Top Dressing & Soil Smoothing

I designed this lawn leveller to create a practical, printable alternative to large metal lawn levelling rakes.

The model is split into three printable parts to improve printability, reduce warping, and make replacements easy:

Included Parts

• Center Base ×1
  Main structural section of the leveller.
• Shaft Mount ×1
  Attaches a standard shaft/rod/handle 28-30mm to the tool.
• Side Wings ×2
  Extends the levelling width while keeping prints manageable.

Once assembled, the tool creates a wide and stable levelling surface ideal for:

• spreading top soil
• smoothing uneven lawns
• distributing sand
• evening out fresh grass seed areas
• preparing garden surfaces

Design Goals

• Easy to print on standard printers
• Modular and replaceable parts
• Strong structure with minimal support requirements
• Compact prints that assemble into a larger tool
• Compatible with commonly available rods/shafts

Print Recommendations

Recommended Material

• PETG (recommended)
• ASA/ABS for higher outdoor durability
• PLA possible for light use

Assembly

1. Print:
   • 1× center base
   • 1× shaft mount
   • 2× side wings
2. Remember to let model cool down completely(!) before mounting/tightening bolts
3. Attach the wings to the center base.
4. Mount your preferred shaft/rod/handle.
5. Tighten hardware and start levelling.

Hardware

Insert 8xM6 thread inserts into the base and fasten wings with 4+4 M6 bolts
or

Use M6 bolts and nuts to attach wings to base
